skl_dsp_ctx_init is dumplication of sst_dsp_new and usage of such bypasses natural DSP framework's flow. Remove it and reuse sst_dsp_new constructor which invokes sst specific init internally so nothing is missed.
Skylake does not even define any sst_ops::init so portion of existing skl_dsp_ctx_init can be regarded as DEADCODE.
